In this study, a model reference adaptive sliding mode speed controller (SM-MRAC) for a direct drive wind energy conversion chain is presented. The system model includes a wind turbine with horizontal axis driving a permanent magnet synchronous generator (PMSG) through a rectifier connected to the dc-bus. The designed SM-MRAC controller is compared with a conventional PI controller. The model and...
As per modern electrical grid rules, Wind Turbine needs to operate continually even in presence severe grid faults as Low Voltage Ride Through (LVRT). Hence, a new LVRT Fault Detection and Identification (FDI) procedure has been developed to take the appropriate decision in order to develop the convenient control strategy. To obtain much better decision and enhanced FDI during grid fault, the proposed...
